Hinokio: Inter Galactic Love 2005

Hinokio: Inter Galactic Love: A recent accident has left Satoru Iwamoto, an elementary school student, temporarily wheelchair-ridden. In addition, the recent loss of his mother has thrown Satoru into a reclusive state, locking himself from the outside world. However, in an effort to help Satoru recover from his injuries, his father, Kaoru, has designed a remote-controlled robot that will go to school in his place and allow him to interact with people and do normal things.
